1. A system comprising:
a cannulated tubular body;
a first cannula connected to an expandable balloon enclosed by an expandable metal mesh, the first cannula configured to pass through a working sleeve and to expand the expandable metal mesh within a surgical site;
a pedicle screw coupling positioned at a first end of the cannulated tubular body, the pedicle screw coupling configured to couple to a pedicle screw in a manner that the pedicle screw can be driven while the pedicle screw coupling is rotated;
an internal shaft positioned within the cannulated tubular body, the internal shaft having a threaded portion which protrudes from the first end of the cannulated tubular body; and
a cement cannula positioned within an inner portion of the internal body, the cement cannula configured to supply bone cement to a coupled pedicle screw through a cannulation of the internal shaft and to remain within the inner portion while the pedicle screw coupling is rotated.
